[Industrial applications]

 The present invention relates to a pillow that is more comfortable than before.

[0002]

[Prior art]

 BACKGROUND ART Pillows filled with cotton, buckwheat hulls, rice hulls, etc. have been known for some time. This pillow is stable when the person's head is stationary.

However, since the height of the pillow is predetermined, there is a problem in that the height cannot be adjusted to an appropriate level.

[0006] Furthermore, since the buckwheat shell or the like filled inside does not follow the movement of the head so much and is difficult to be deformed, the head and neck are fixed to some extent during sleep, and a feeling of restraint is felt. There was a problem that accompanied. Therefore, when turning over, the neck and other parts of the body may be overloaded, which may cause sleep to occur.

[0005]

[Problems to be solved by the device]

 Therefore, this invention seeks to provide a pillow whose height can be adjusted. Moreover, after solving the said subject, it is going to provide the pillow which is harder to apply to the neck etc. than before when rolling over.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, this invention takes the following technical means.

The pillow of the present invention is characterized in that it has a head-mounting shape and is provided with at least two layers of bag portions including an air layer into which air is to be injected.

Alternatively, the layer containing the gel-like material may be separated into an air layer and an air layer to form two layers.

In addition, a plug is provided in the bag portion for containing the gel-like material, a gelling agent is arranged in the bag-like portion, and water is injected into the bag portion at the time of use to make the gel-like material. You can also do it.

It is also possible to weld the central portion of the bag portion over the front and back sides and form the central portion into a recessed shape.

[0011]

[Action]

 This device has the following actions.

Since the pillow of the present invention has a shape in which the head is placed and has at least two layers of bag portions including an air layer into which air is to be injected, the amount of air to be injected into the air layer can be adjusted. By doing so, the height of the pillow can be appropriately set.

When the layer containing the gel-like material is separated into an air layer and the upper and lower layers to form two layers, the layer containing the gel-like material is said to be filled with buckwheat hulls or the like. Compared to it, it is easy to deform by following the movement of the head.

If a bag is placed in the gel-like material, a gelling agent is placed in the bag, and water is injected into the bag during use to make a gel-like material, which can be sold or sold. In this case, since it is low in volume and can be in a lightweight state, it can be handled easily.

When the central portion of the bag portion is welded to the front and back to make the central portion dented, the head can be stabilized by following the dent when used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the drawings showing the embodiments.

As shown in FIGS. 1 and 2, the pillow of this embodiment is made by putting a gel-like material 1 in a bag formed and processed by a known method in a shape in which the head is placed by a synthetic resin. It is supposed to be. Polyurethane resin, which is a synthetic resin that can expand and contract to some extent, is used as the material for the bag material.

As shown in FIG. 2, the layer containing the gel-like material 1 is separated into an upper layer and a lower layer with an air layer 3 through a partition wall 2 made of an intermediate poly-urethane resin to form two layers. There is. The air layer 3 is provided with a plug 4 (having a publicly known check valve) on the outer wall so that air can be taken in and out. Therefore, there is an advantage that the height of the pillow can be appropriately set by appropriately adjusting the amount of air to be injected into the air layer 3. In addition, the volume of the gel-like material 1 required to obtain an appropriate pillow height when sleeping is smaller than that in the case where only one layer containing the gel-like material 1 is used. There is also an advantage that the weight can be reduced.

The bag portion 5 for containing the gel-like material 1 is also provided with a stopper 6. This stopper 6 also has a structure having a publicly known check valve, so that the gel-like material 1 contained in the bag portion 5 does not leak during use. It should be noted that the gel 1 is less likely to leak than water and the like, and even if it leaks, it is less likely to spread like water.

A gelling agent (not shown) is arranged in advance in the bag portion 5 in which the gel 1 is placed. Then, at the time of use, water is injected into the bag portion 5 to make the gel-like material 1 from the gelling agent. The gelling agent has a very small volume when it is not given water. Therefore, this pillow can be folded to be in a low-bulk and lightweight state when it is not infused with water, such as when it is sold or carried, and its handling can be simplified. There is an advantage.

As the gelling agent, in this example, a known acrylic water-absorbing polymer that gels by including water (high-speed water-absorbing resin, commercially available from Sanyo Kasei Co., Ltd., Mitsubishi Kasei Co., Ltd., etc.) ) Was used in an amount of about 30 g. The pillow can also be adjusted to be stiffer by increasing the amount of water injected. Instead of the water-absorbing polymer as the gelling agent, a surfactant or the like may be used.

The central portion 7 of the bag portion 5 is welded on the front and back sides by a known method to form a hollow central portion. Therefore, there is an advantage that the head can be stabilized by keeping the head along the depression when sleeping.

Next, the use state of the pillow of this embodiment will be described. At the time of use, about 3 liters of water was poured into the bag portion 5 in which about 30 g of the gelling agent was placed in advance to make the gel 1 from the gelling agent, and the stopper 6 was sealed. At this time, the volume of the water-absorbing polymer used as the gelling agent expanded to about 100 times the original volume. Further, the amount of air was adjusted to be injected into the air layer 3, the height of the pillow was adjusted to an appropriate level, and the stopper 4 was sealed. In addition, once water and air are injected, it can be used until then.

A bag formed into a shape for placing the head and containing the gel-like material 1 can freely follow the movement of the head as compared with a pillow or the like which is filled with buckwheat shells or the like and which is poor in morphological variation. Easy to deform. Therefore, there is an advantage that it is difficult for the neck and the like to be forced when turning over. In other words, it can follow and transform unconscious body movements during sleep with little resistance, relax the head, neck, shoulders, etc. and make the wakeup comfortable.

Further, the pillow of this embodiment is superior in shape retention and stable as compared with the pillow in which water is sealed. Therefore, there is an advantage that the head is less likely to wobble. In other words, it is excellent in fit to the cervical spine and the like during sleep, and it is possible to secure a certain degree of free movability without excessive fixation while fitting.

When using, a pillow cover (not shown) made of fabric or the like is placed on the outside of the pillow so that there is air permeability between the pillow and the body made of poly-urethane resin cloth. By doing so, stuffiness is less likely to occur and the direct coldness of the gel material 1 can be relaxed.

Further, the pillow of this embodiment has a refreshing feeling at room temperature, which is lower than the body temperature, and when placed in a large refrigerator and cooled, it feels cooler and more comfortable. .

Furthermore, since the gel-like material 1 containing water has a heat capacity of about 3 liters, the residual heat of the head can be naturally removed during sleep.

Note that the pillow can be implemented as a pillow having a two-layer structure including an air layer and a water layer. In this case, you can enjoy the cool air with the water layer on the upper side in the hot season such as summer, and you can enjoy the soft feeling with the air layer on the upper side in the cold season such as winter.
